OEMC representatives said people should call 911 if there’s an emergency during the heat wave. They can also call 311 tou request a well-being check on a relative, friend, or neighbor; or to locate a cooling center.

Aside from a cooling center, if you don’t have air conditioning at home, you can go to police stations, libraries, park district buildings, hospitals, and other public buildings to keep cool.

“I can’t emphasize enough how important it is for everybody to look out for each other, especially our vulnerable population. Talk to your neighbors, talk to your friends, the people you care about,” Office of Emergency Management and Communications director Rich Guidice said Thursday.
